Windows Phone Dev Build unable to restart once phone disconnected

For the last few days I’ve been struggling with Unity development builds on my Windows Phone (L920, 8.1). I can build them and they run as long as they are started from Visual Studio Express 2012 for Windows Phone or Visual Studio Community 2013, but after a disconnect they crash immediately after start (not even the splash screen is displayed).

And btw, what exactly do the numbers on the right side mean (while running from VS)? The first one is fps I guess, but I don’t know the others. The second one is 1 and is red, is that a problem?

When an application crashes when not started from Visual Studio, the phone will create a crash dump in Documents\Debug folder on the phone, so you can transfer that dump file to PC, debug it and figure out what happened.
